So, there’s this parallel universe that’s being faced with some sort of reality-based threat to do with the degradation of their Hume field. So, parallel-universe-Foundation gets the brilliant idea to screw over another universe to save their own. This happens to be our universe.

So, sometime in the 1900s (in our universe,) there’s a massive explosion in a secluded area somewhere. I might try to tie this in with the Tunguska explosion, but maybe that’s unnecessary. A team is sent out to investigate, which leads to the discovery of the anomaly.

So, the actual anomaly would be some sort of monolith or other object, that materialized right in the epicenter of the explosion. Its effect is that it causes the total breakdown of reality in a certain radius around it, which is slowly but continuously expanding, suggesting that the parallel universe is siphoning our Hume field into their own.

As for the actual effects something like the breakdown of reality would have, I’m open to suggestions. Maybe it could be similar to what happened to Scranton in 3001, except an object that enters this anomaly’s radius would have its Hume field equalize much more rapidly and aggressively, first being deconstructed into simple shapes and elements, and eventually being completely destroyed.

I think this could make for some good exploration logs, and I could do a lot with the backstory of it. Maybe some communications with the parallel universe’s Foundation, similar to in that article with the knife that tears rifts between universes (can’t remember the number off the top of my head.)

What do you think? I’m open to any suggestions! Feel free to tell me if my understanding of Humes is completely wrong.

This caught my interest immediately. I like the idea of multiple Foundations clashing against each other for the survival of their own reality. Although, I'm left with one question: why do they think destroying our universe will suddenly save theirs?

suggesting that the parallel universe is siphoning our Hume field into their own.

So, the monolith is actually stealing our reality's stability and transferring it to the other's? This is completely original as far as I'm aware. I do think, though, that it should be stressed that it's not destroying our stability, rather, it's just stealing it.

I think this could make for some good exploration logs

What exploration logs could there be? Would an object that gets close to the SCP transfer to the other universe? What's the true difference between our reality and theirs?

I assume it’d be some sort of last-ditch effort by the Foundation. Ideally they’d have this thing specifically designed to siphon Humes. Of course, they have no idea whether it’ll actually work, but it comes down to not really having any other options.

Sounds like SCP-804.

Mm. You’re right. Considering the “siphoning Humes” is the whole gimmick here, I’m not really sure how I could make it different.

What exploration logs could there be?

Honestly that was more of an offhanded comment than anything. I didn’t think too deeply about what would actually be in the logs. With this kind of anomaly I might have trouble avoiding the “MTFs go in and then everything goes wrong and they die!” cliche.

A vague idea I have is where the MTF enters the anomaly’s radius and there would be a lot of visual imagery of the surroundings becoming increasingly screwed up as the laws of physics lose their grip over the squad. I might need some more creative advice here.

Would an object that gets close to the SCP transfer to the other universe?

Maybe. That could be an interesting twist on the anomaly, and maybe act as an unintended repercussion for the other universe.

What’s the true difference between our reality and theirs?

Maybe I’m misunderstanding the question, but there isn’t much difference. All that would be different is that in their universe, some sort of weird reality-degradation event started that necessitated the creation of this SCP.

I'll reply with more feedback sometime tomorrow. Be sure to come back to this post to see if it's been edited!

This is an interesting take. They know that their reality is ending, and so they say "fuck it" and try to screw over some other universe because (they think) it doesn't really affect them. Here's an idea for a narrative: it does.

I might have trouble avoiding the “MTFs go in and then everything goes wrong and they die!” cliche

This is a cliche that I'm particularly fond of if done right. Having MTF die for no reason is a horrible idea, but, if you can add some audio logs in there that is a much more interesting death than "he disappears in midair" or "he got shot," it shouldn't be a problem.

I like the idea you've presented us with the exploration logs here. There is only one remaining question if you decide to go with this (which I hope you do): where do they go when the grip on the task force is lost?

Maybe I’m misunderstanding the question, but there isn’t much difference.

I don't think you misunderstood, because you managed to answer my question.
